RAINFALL TIME SERIES ANALYSIS

Abstract

It is now generally acknowledged that greenhouse gas emissions are to be blamed for the rise in the global average temperature. Changes in the frequency of extreme weather occurrences, such as catastrophic floods, storms, and droughts, may indicate global warming drought. On a global scale, the subject of climate change is being discussed. In the age of climate change and global warming, we set the goal of this study to analyses the rainfall trends in Cherrapunji. Data on the station's monthly rainfall is the 48 years is observed and the graphs are plotted showing the monthly rainfall time series of Cherrapunji over a time period of 48 years along with the linear trendline, trendline equation and R-squared value is compared and the time series graphs are analysed month wise and season wise. Since Cherrapunji receives heavy rainfall throughout the year, so we broke down the data into five seasons and also carried out the seasonal analysis of rainfall. This station was chosen because it had more readily available data and it represented the area with the most rainfall records.
